Very good looking accurate watch but,
Color: Black
As others have said buttons very hard to operate. I'm not sure if it's by design or if they released an abnormally tough run, but they do require intent and strength to push. On the bright side, you'll never (and I repeat NEVER) accidentally press the button and activate something. You have to try hard to push them intentionally, I don't think it's even possible to accidentally press one. The look and feel of the watch are great though and I think the band is actually better quality than most Casio bands. Overall the price increase over similar casios gets you - better light, nice slim profile, and a better band, as well as buttons that won't accidentally push (because they're so tough to lol)

Defective watch - after 1.5 months of use, time automatically reset every day
Color: Teal/Brown
I'd only had the watch for about 1.5 months before the time started to automatically reset without any apparent reason. I would set it to the correct time, then before the day was done, I would look down and see that the watch time was drastically incorrect. I've seen at least one other review on Amazon describing this same problem with the Atlantis.
Other than that, as other reviewers have mentioned, the buttons are a bit hard to press but that isn't a dealbreaker in my opinion (you get used to it). If you like the way the watch looks, and want a simple, smaller, lightweight digital watch, the Atlantis is adequate, especially at this price point - assuming it's not defective like mine.

It’s an “OK” watch.
Color: Black
I just received this watch. The watch fits well and is comfortable, light weight and is thinner than others I have had, which I actually like. There is no manual and trying to find one on line is a tall order. I just fiddled around with it to figure it out. Still working on some of the features. It apparently has two time settings which is good if you travel to other time zones without having to reset your time. Just hit the button. Speaking of the buttons, they are pretty tough to push. The display is so-so; some may have difficulty reading it although the numbers for the time are larger. It’s a decent watch but being worth $42 remains to be seen.
I was a bit unhappy to receive the watch in an Amazon paper bag envelope. The box was crushed but the watch was in tact. It really should have been shipped in a box.

Perfect watch
Color: Black
This is the perfect watch for me. No negative issues at all. It's light, comfortable, easy to read, accurate, and tells me exactly what I want to know, even in the dark. I like that the seconds can be reset to zero with the push of a button. That makes it easy to set the time to the second. Battery replacement is simple. No pressing the back on with a watch press. I will agree the buttons are a bit stiff, but then I can't accidentally press 'em by flexing my wrist.
